Piston head for french press coffee maker

Abstract

An attachment system for connecting a piston cover to a piston body of a french press coffee maker comprises a plate having a top surface and a bottom surface. The bottom surface of the plate is adapted to be in contact with a top surface of the piston cover. The bottom surface has at least one peg extending therefrom. The at least one peg is adapted to be inserted into at least one aperture of the piston cover and corresponding at least one aperture of the piston body. The at least one peg is adapted to be secured to the bottom surface of the piston body. Piston heads for a brewing chamber of a french press coffee maker are also presented.

I claim: 
     
       1. A piston head for a brewing chamber of a French press coffee maker, the piston head comprising:
 a piston body having a top portion and a skirt extending downwardly from the top portion, the top portion having a top surface and a bottom surface, the bottom surface being adapted to be pivotally connected to a piston rod; 
 a piston cover mating at least a portion of the piston body, the piston cover having a top portion and a skirt extending downwardly from the top portion, the top portion having a top surface and a bottom surface, the bottom surface of the piston cover mating the top surface of the piston body, the skirt of the piston cover mating at least in part the skirt of the piston body; 
 a holding plate connecting to the piston cover and the piston body, the holding plate having a continuous flat top surface, at least one hollow peg extending from a bottom surface of the holding plate through at least one aperture of the piston cover and through at least one aperture of the piston body, the at least one hollow peg securing the holding plate to the piston body, the top surface of the piston head being said continuous flat top surface of the holding plate, wherein said continuous flat top surface is adapted to be in contact with an inside of the brewing chamber; 
 at least one screw being inserted in the at least one hollow peg for securing the holding plate to the piston body. 
 
     
     
       2. The piston head of  claim 1 , wherein the skirt of the piston body includes at least one groove; and
 further comprising a seal disposed at least in part in the at least one groove, the seal being disposed between the piston body and the piston cover. 
 
     
     
       3. The piston head of  claim 1 , wherein the piston body and piston cover are each generally circular. 
     
     
       4. The piston head of  claim 1 , further comprising an indentation on the skirt of the piston cover. 
     
     
       5. The piston head of  claim 1 , further comprising at least one washer disposed between the at least one screw and the bottom surface of the piston body. 
     
     
       6. The piston head of  claim 1 , wherein the top surface of the holding plate has a raised central portion. 
     
     
       7. The piston head of  claim 1 , wherein the at least one peg includes at least two pegs, the at least one aperture of the piston cover includes at least two apertures, and the at least one aperture of the piston body includes at least two apertures. 
     
     
       8. The piston head of  claim 7 , wherein the at least two pegs and the at least two apertures of the piston cover and piston body are disposed radially relative to a center of the holding plate. 
     
     
       9. An attachment system for connecting a piston cover to a piston body of a French press coffee maker, the attachment system comprising:
 a plate having a top surface and a bottom surface, the bottom surface of the plate being adapted to be in contact with a top surface of the piston cover, the bottom surface having at least one peg extending therefrom, the at least one peg being adapted to be inserted into at least one aperture of the piston cover and corresponding at least one aperture of the piston body, the at least one peg being adapted to be secured to the bottom surface of the piston body; 
 at least one screw, the at least one screw being adapted to be inserted in the at least one peg for securing the holding plate to the piston body. 
 
     
     
       10. The attachment system of  claim 9 , further comprising at least one washer adapted to be disposed between the at least one screw and the piston body.
